Song with the best vocals (skill wise) on each studio album?
I'm not a professional so take this with a pinch of salt but for me it's probably:
Showbiz - Showbiz. Not much to say here, great song and great vocals.
Origin Of Symmetry - This one is hard but honestly maybe Megalomania. The range in this song is great. Micro Cuts is obviously up there and I think Futurism is quite high, especially for a bonus track.
Absolution - Sing For Absolution. Purely for the last minute or so of the song. Incredible. Fury might be up there as well.
BH&R - Take A Bow or Hoodoo are up there, but the songs on this album feel mostly at a similar level. Glorious is also good for vocals.
The Resistance - Probably Reistance or Overture, though I think I Belong To You deserves more recognition when it comes to vocals.
The 2nd Law - Survival mostly for that high note. Supremacy because it has amazing range and madness for the end of the song are both up there.
Drones - Dead Inside. I don't know if it's just because the 2nd half of this song id what makes it one of my favourite muse songs, but I love it.
Simulation Theory - Dig Down. As much as people mock it, that long "Dig down" high note is good.
Will Of The People - Ghosts. Might be an easy pick because it's a ballad, but I do love the vocals in this song.
The Wow! Signal - Space Debris. Similar to what I said for the last album but I do think the last chorus of this song is very good. Unravelling is up there as well.
